    Echinoparyphium aconiatum (Digenea: Echinostomatidae) is an intestinal parasite of anatid and snail-eating birds. In Eurasia, it is also common in lymnaeid snails, which may serve as the first and second intermediate hosts. The systematics of its genus, Echinoparyphium, have long been inadequate, with poor descriptions and extensive synonymy. To provide a basis for developing new genetic markers for studies of the identification and systematics of echinostomatids, the complete Ep. aconiatum mitogenome is described and compared with other digeneans. The circular mt molecule of this species is 14,865 bp in length, with an average A + T content of 64.33%. It contains 12 protein-coding genes and 22 transfer RNA genes. The 3′ end of nad4L overlaps the 5′ end of nad4 by 40 bp, while the atp8 gene is absent. Twenty-one transfer RNA genes transcribe products with conventional cloverleaf structures, while one transfer RNA gene has unpaired D-arms. Comparative analyses indicate that Echinoparyphium aconiatum is closely related to Echinochasmus japonicus and Echinostoma miyagawai. The phylogenetic results, using our mitochondrial data indicated Ep. aconiatum as a sister taxon of Hypoderaeum conoideum in a monophyletic clade. Our data and analyses serve as the first representative sequenced mt genome from genus Echinoparpyhium, providing additional markers to clarify the taxonomic position of Ep. aconiatum.

    Chattonella verruculosa Y. Hara et Chihara was re-examined by molecular methods and microscopic examination. The 18S rDNA phylogenetic analysis clearly indicated that C. verruculosa is a member of the Dictyochophyceae, with a specific affinity to Florenciella parvula. The morphological features in C. verruculosa - namely the proximal helix with two gyres and many scattered DNA-containing areas in the chloroplasts - display the evolutionary link to the Dictyochophyceae, instead of the Raphidophyceae. Similarly, unique pyrenoid morphologies are shared between C. verruculosa and the dictyochophycean algae. Combining the molecular data and morphological characteristics, C. verruculosa is transferred to Pseudochattonella gen. nov. of the class Dictyochophyceae as Pseudochattonella verruculosa (Y. Hara et Chihara) Hosoi-Tanabe, Honda, Fukaya, Inagaki et Sako comb. nov.

    The dinoflagellates Alexandrium tamarense (Lebor) Balech and Alexandrium catenella (Whedon and Kofoid) Balech (Dinophyceae) are believed to be the main species responsible for paralytic shellfish poisoning (PSP) all over the world. It is necessary to identify A. tamarense and A. catenella cysts and to monitor their distribution in sediment in order to minimize the damages caused by PSP to the economy and food quality because cysts are the seed population for blooms caused by motile vegetative cells. In this study, we developed an efficient DNA extraction method from the natural cysts present in marine sediments after they were size fractionated with a plankton net (mesh size of 20-150 mu m). The 10-3000 cysts were added to the sediments collected from the Ariake Sea, and for which the primuline-staining method did not reveal any cysts. DNA was then extracted from each sample, and linear standard curves for A. tamarense and A. catenella cysts were obtained from the correlation between the Ct values by real-time PCR and the log of the initial densities of cysts. We monitored the A. tamarense and A. catenella cyst densities in the environmental samples. This assay was demonstrated to be a powerful tool for the identification, detection, and quantification of the cysts of the toxic dinoflagellates. (C) 2007 Elsevier B.V. All rights reserved.

    Disposal of the seaweed wakame (Undaria pinnatifida) by inoculating the halotolerant bacterium Bacillus sp. HR6 was examined in an experimental scale composting system. Strain HR6 was effective in initiating the composting process of wakame, and there was a rapid increase in temperature to over 54.9-55.7°C after 18-20 h. The composting process of wakame could be carried out despite a high NaCl content, 28.2 mg/g, although lower salinity resulted in a shorter lag time and higher weight reduction. In a larger scale composting process with aeration, two peaks of temperature change were found which corresponded well to oxygen consumption and CO2 emission during the process. The pH increased to 8.83 and organic materials were reduced to 93.4 % after 72 h. The initial N and C contents were 3.9 and 34.0 %, respectively, both of which decreased during the composting process. The changes in the viable cell numbers suggested that strain HR6 predominated before 24 h and other microorganisms including HR6 were present in a mixed state during the later period of composting. The total content of alginate (TA), 32.2 % in the initial stage, decreased to 29.2 % after 72 h, while water soluble alginate (WSA) increased, indicating that the solubilization and decomposition of alginate had occurred during the composting process.

    The genetic relationship between the toxic marine dinoflagellates Alexandrium tamarenseand Alexandrium catenella, which share similar morphological characteristics and are clustered as a sister group on the phylogenetic tree based on 28S rDNA analysis was examined by DNA-DNA hybridization. This method has contributed to the information on relative comparisons of total sequences in the field of microbiology
    however limited DNA-DNA hybridization studies have been carried out on microalgae, including dinoflagellates. The intragroup homology of DNA-DNA hybridization within the A. tamarense and A. catenellagroups, that was identified on the basis o morphotypes, was 85.0%-99.8% in both cases, whereas the intergroup homology between these two groups was 62.5%-70.3%,which was lower than the intragroup homology. These percentages revealed that not only the rDNA sequences but also the total sequence reflects slight morphological differences between A. tamarenseand A. catenella, indicating the possibility that strains identified as these two species could be differentiated as distinct groups based on the percentage obtained using DNA-DNA hybridization. The homology of A. tamarensewith other Alexandrium species was low-37.1%-45.2% with A. tamiyavanichii, 41.0%-45.5% with A. affine, and 24.8%-35.8% with A. ostenfeldii. The relatedness between A. catenellaand other Alexandriumstrains tested (e.g. between A. catenellaand A. tamiyavanichiiwas 39.0%-51.2%) was also lower than that between A. tamarenseand A. catenella. Further, these percentages were consistent with the rDNA phylogenetic analysis, indicating that DNA-DNA hybridization might be a useful tool to understand the relatedness among Alexandriumspecies. © 2006, The Plankton Society of Japan, The Japanese Association of Benthology.

    The marine toxic dinollagellates Alexandrium tamarense (Lebor) Balech and A. catenella (Whedon and Kofoid) Taylor that cause paralytic shellfish poisoning (PSP) are identified on the basis of morphological features in routine monitoring. Rapid and simple identification is, however, often difficult because of the morphological similarity. Fluorescent in situ hybridization (FISH) using ribosomal RNA (rRNA)-targeted probes has been studied as a method of easily identifying and enumerating species responsible for harmful algal blooms (HABs). Its application to monitoring natural populations of HAB species, however, is limited. Here, we applied the FISH method to identify and enumerate cells of A. tamarense and A. catenella in natural plankton assemblages collected from Japanese coastal waters. A. tamarense-specific (Atm1) and A. catenella-specific (Act1) probes were established based on the D2 region of the large-subunit ribosomal RNA gene (28S rDNA). With these two probes, natural cells of A. tamarense or A. catenella in field samples could easily be identified when the following three conditions were met. First, cells should be concentrated by filtration, not centrifugation, in order to avoid the loss of cells. Second, autofluorescence should be minimized; acetone was an effective decolorization reagent. Third, samples should be stored at -20 or -80 degreesC for long-term preservation. The results indicate that FISH is a useful tool for the rapid identification of toxic Alexandrium. spp. and can facilitate the analysis of numerous natural samples. (C) 2004 Elsevier B.V.
